Lyne Saddle Vast 143
What Is It?
The Lyne Saddle Vast 143 is a performance-oriented bicycle saddle with a 143mm width, designed for MTB, gravel, and road riders who want a balance of comfort, pressure relief, and efficient pedalling position.
The “Vast” shape is typically aimed at supporting riders who stay in a moderately aggressive riding position, distributing weight across the sit bones while reducing soft-tissue pressure through a central relief channel.
